Title: Radial tyre with low internal shear stresses - where inflated carcass remains externally convex between specific points
Inventor: YAMAGISHI KOICHI
IPC: B60C9/08
Filed: 1979-04-06
Abstract: A narrow-section radial tyre has an annular tread, two sidewalls from tread to beads, bead wires, internal reinforcement carcass and rubber layer between beads with radial cord filaments, and a girdle beneath the tread and round the carcass; the ratio of the height from the foot of the bead to the top of the carcass section to the max. carcass width is is not >0.8. When the tyre is mounted on the rim and inflated, the profile of the carcass is convez outwards and concave inwards, the convex section extends from a specific point and in the plane which passes through the rim where that is at right angles to the axis of rotation near the bead, along the sidewall and to the tread; this convexity is maintained in equilibrium so that it only balances the inflation pressure, the girdle, and the reaction to the inflation pressure; the concave section extends from near the same point to the bead wire area, it is held by the rim and blends continuously into the convex section. The force carried by the girdle is utilised to produce an equilibrium profile of the carcass, and reduced shear stresses in service.

Title: Sequentially operating program control for machine tool - has computer unit to derive successive values of radial, height and carriage position vectors for machine tool tops
Inventor: SCHRAGO LEONID KONSTANTINOVITS
IPC: G05B19/4093
Filed: 1979-06-05
Abstract: The machine tool operating cycle is based on a sequence (i) of radial (A), height (Z) and carriage movement (X) vectors for a number of machine tool tips (21, 22...) operating on the workpiece (1) to perform various operations (11, 12..). Each movement is co-ordinated with an origin (D1) 1=1, 2.. for the initial position of the machine tool tip, and subsequent movements are calculated by a computer which coordinates the movements of each of the tips (21, 22...). The computer unit is connected in a logic circuit with AND gates and OR gates, a reversible counter, a register unit for dimensional information and a feedback circuit to calculate error correction signals derived from a carriage and tool position sensor.
Patent DE-2926835-A1 (DE)
Inventor: BASS DIETER DR
IPC: B22D31/00
Filed: 1979-07-03
Abstract: The apparatus has a tapered drum, which has the filling region (40) at its smaller-diameter end and the ejection region (45) at the opposite end. Its axis (21) of rotation extends at an upwardly inclined angle in the feed direction, the generating line (16) at the bottom in longitudinal section sloping downwards. It is thereby possible to achieve a big charge (17), a long dwell time and better cooling and, as a result, a shorter drum length. <IMAGE>

Title: Accessible and transportable building material container - is made from trapeze shaped angle sections inserted into square frame
IPC: E04H1/12
Filed: 1979-10-18
Abstract: The accessible and transportable building material container is built from trapeze shaped members inserted into a square shaped frame. All the frame sections are made as similar angle profiles (1,2,3) connected at the junction points with a triple surfaced corner connector (4). The angle profiles made from metal strips edged so that the edge surfaces (6,7) of an angle iron (5) are bent over twice at about the same width each by about 90 degrees inwards. This ensures that a distance remains between the edge surface of one side of the angle profile and the opposite side edge of the angle profile lying parallel to it which corresponds to the height of the trapeze shaped irons.

Title: Appts. for vat dyeing cotton warp yarns - in sheet form, offers multiple dyeings
Inventor: GODAU ECKHARDT
IPC: D06B23/06
Filed: 1979-12-21
Abstract: The vat dyeing of cotton warp yarns in sheet form comprises passage through a dye bath, with removal of excess dye liquor, passage through air and/or thermal treatment; this series of phases is repeated several times. A single dyebath, nip device and air passage are used, and the sheet of warps is looped several times to repeat the treatments before washing and rinsing. A relatively small volume of dyebath liquor is required to provide a very uniform and intense colour effect throughout the warp sheet, with possible adjustment of shade. The dyeing appts. is simple and compact. Easy control of the chemical balance and concn. of the dyebath is practical over a wide range of shades.

Title: Hydraulic pit prop regulating system - has after-setting unit ahead of relief valve activating operating piston
Inventor: KRIEGER KARL
IPC: E21D23/16
Filed: 1980-03-29
Abstract: Two two-way valves alternately subject the two piston sides of a prop to pressure fluid from a high-pressure load, and connect the non-subjected side to a return lead, in controlling hydraulic props in a striding support system in a mine. An after-setting device (W) for the prop is switched into the prop-setting lead (3), in advance of the prop relief valve (8). When a prescribed min. setting pressure is built up, this activates an operating-piston (23), activated against spring (5) force. With this min. pressure established, it automatically terminates pressure supply to the prop (1).

Title: Position location system for vehicles on predetermined routes - contains position coding units and vehicle transducer and computer
Inventor: RIBHEGGE RUDOLF ING GRAD
IPC: G01C22/02
Filed: 1980-04-18
Abstract: An arrangement for determining vehicle position on a predetermined route contains position code devices transforming instantaneous position to the vehicle point by point. The vehicle has a distance pulse transducer and a computer on board. The system is designed to enable the vehicle to repeatedly and automatically generate correction factors for distance errors. Along the predetermined route the vehicle passes through one or more calibration sections whose beginning and end are communicated to it via the position coding units. The computer automatically derives a correction factor from these inputs and takes account of it in summing the pulses from the distance measurement transducer. The beginning of the section is identified by a special bit pattern from a code unit. The end is identified by a normal message from the next unit.

Title: Non-dispersive IR gas analyser beam receiver - eliminates spectral interference by using non-selective absorption wire elements
Inventor: FABINSKI WALTER ING GRAD
IPC: G01N21/37
Filed: 1980-09-19
Abstract: A radiation receiver for a non-dispersive, infrared gas analyser with a periodic beam interruption device consists of two gas chambers (1,2) in series in the beam path. A pneumatic-to-electric transducer (3) converts the chamber pressure difference into an electrical signal. It eliminages the errors encountered when gas components in the mixture being analysed have absorption bands which interfere with measurement component absorption bands. This is achieved by partially blocking the cross-section of the first or second chamber with them, low thermal inertia elements (8) which absorb the incident radiation non-selectively. The elements may be in the form of blackened wires, or a single wire element may be used. They are placed in the first or second chamber according to the type and degree of spectral interference. (Specification printed 7.1.82).

Title: Controlled mfr. of saturated solution - in two-compartment container with meter for admitted and extracted solvent
Inventor: LEDALL GUY
IPC: B01F1/00
Filed: 1980-11-28
Abstract: A saturated solution of a solid, e.g. common salt, in a solvent, e.g. water, is based on introducing a metered amount of the solvent into an excess of solids. The contact between them is maintained long enough for the dissolution of the solid. The solution produced is extracted and the difference between the volumes of admitted and extracted solvent is taken as the quantity of dissolved solid. This indicates the degree of dissolution of the solids and can be used to actuate an alarm when the concentration of the solution is under pa#.
